Decipede

A crawler of ten amber beads with a violet head enters at the top left and runs across a field of crystals. When a crystal or the side blocks it, it steps down a row and turns back; once at the bottom it stays in your gun zone for good. A red, poisoned crystal makes the head dive straight down. Your gun moves in the bottom four rows and fires one shot at a time. Any bead hit takes one bead off the end of the crawler for 50 points; ten hits clear the wave. Crystals break for 25. One pest at a time joins in: the zigzagging HOPPER, the DROPPER that plants crystals above you, and the CREEPER that poisons them. A head, hopper or dropper touching your gun costs one of three guns.

Controls: Use either controller. The stick moves the gun and either button fires; hold it to keep firing.
